“Would you be surprised to learn that Foss’s head has been picked up on Chobham Common?” he asked.

The other turned a pair of cold, searching eyes upon his interrogator.

“I should be very much surprised,” he said coolly. “If necessary, I have a witness to prove that Foss went, though I don’t like bringing in a lady’s name. Miss Stella Mendoza was here, having a bit of supper, as you probably know, if it was you in the next room. He left before she did.”

“And he returned,” said Michael.

“I never saw him again, I tell you,” said the baronet violently. “If you can find anybody who saw him come into this house after his first visit you can arrest me. Do you think I killed him?”

Michael did not answer.

“There was a woman upstairs in the tower. What has become of her?”

The other wetted his lips before he replied.

“The only woman in the tower was a sick servant: she has gone.”

“I’d like to see for myself,” said Michael.
